Away3D 4.0 and Diffuse Lighting! Software: Away3D 4.x

empend, Member Posted: 06 October 2011 05:11 AM Total Posts: 77 After trying to figure it out, I can’t. I’m loading a model, and trying to apply lighting to its material, but I only get the specular lighting! Is there any reason why this would happen? If anyone needs to code I’ll share it. I hope someone can help.

Richard Olsson, Administrator Posted: 06 October 2011 04:17 PM Total Posts: 1192 [ # 2 ] Just modify the material lighting properties. Tweak the specular and diffuse properties to decrease the amount of specular light, and increase the amount of diffuse light. It should work just fine. Are you sure you’re not referring to ambient light? Because if you need that, tweak the ambient and ambientColor properties. Make sure none of them are 0/black.
empend, Member Posted: 06 October 2011 04:22 PM Total Posts: 77 [ # 3 ] I got the lighting working! I just forgot to add the light to the scene. Now I’m trying to figure out how to get shadows to work! I’ve left the FLA, and all the other assets in a ZIP attached to this post. If someone wants to take a look at it, and add shadows, so I can learn from it that’d be awesome. Unless you would like to just show me how to use shadows another way, because I couldn’t figure out how to get them to work! Thanks to whoever decides to help me! :D File Attachments Away3D_Model_Viewer.zip (File Size: 458KB - Downloads: 222)

empend, Member Posted: 06 October 2011 05:18 PM Total Posts: 77 [ # 5 ] Still not able to get it to work. :( This is the code I use to setup the materials, and models. parser.loadData(event.target.data); var groundMaterial:BitmapMaterial = new BitmapMaterial(new dirtTexture(), true, false, true); groundMaterial.ambient = 0.2; groundMaterial.specular = 0.2; groundMaterial.gloss = 30; groundMaterial.lights = lightList; groundMaterial.shadowMethod = new FilteredShadowMapMethod(directionalLight); var ground:Plane = new Plane(groundMaterial, 30, 30, 1, 1, true); ground.y = -4; container.addChild(ground); var material:BitmapMaterial = new BitmapMaterial(modelTexture,true,false,false); material.ambient = lightAmbient; material.specular = 0.6; material.ambientColor = 0xFFFFFF; material.lights = lightList; material.shadowMethod = new FilteredShadowMapMethod(directionalLight); for (var i:int = 0; i<parser.numChildren; i+=1) { var mesh:Mesh = parser.getChildAt(i) as Mesh; mesh.material = material; mesh.castsShadows = true; container.addChild(mesh); } Apparently view.camera.lens.far was too high, and it wouldn’t display shadows… I’m sorry, but I hate checking my code 20 times to find out something like that ends up being the problem… You should put a comment in the Basic_Load3DS.as example explaining it.

Camera realigns MovieClipSprite when it moves (hovers). Can this be done manualy? ››
